Ungroup allows existing definitions to be modified and the resulting objects recombined with the Group (Group Dialog) command to update the definition. Turnouts are composed of individual straight and curved segments. Segments that form the points (XTrackCAD Terms) of the turnout remain combined as an Ungrouped Turnout, and the other segments are replaced by straight and curved tracks.

One-ended Turnouts (AKA Bumpers) are converted to Staight tracks by Ungroup. These can be converted back to a Bumper by manually editting the Grouped definition and removing the unwanted End-Point by deleting the correspnding E line.
